| 英文摘要 | to elucidate the formation process of hcn from the pyrolysis of glycine, the small molecule gaseous pyrolysates, h2o, nh3, co2, co, hnco, and hcn, were analyzed in real-time by tg-ftir. the appearance of the volatile pyrolysis products and the solid residue was determined in real-time at their corresponding formation temperatures by online py-two-dimensional gc-ms with heart-cutting and lc-ms/ms. the pyrolysis of 2,5-diketopiperazine, a thermolytic by-product of glycine pyrolysis, was also studied. the results showed that: (1) the pyrolysis of glycine can be divided into three temperature ranges 200-300, 300-440, and 440-900 a degrees c; hcn forms in each range with three peaks appearing at 273, 422, and 763 a degrees c, respectively. (2) the mechanistic pathways of hcn formation from glycine in the low- and high-temperature heating stages are different. below 273 a degrees c, glycine undergoes a decarboxylation reaction to produce methylamine, which subsequently forms hcn by means of dehydrogenation. above 300 a degrees c, glycine gives relatively large amounts of hcn via 2,5-diketopiperazine and subsequent hnco or methylenimine formation. |
